The amount of magicians that complain when people want to show them a magic trick is staggering. I don’t get it, why not let the person show you?
The person will be the star for a minute, and I think that’s where the problem is, most magicians have a ego that won’t let them step away and let someone else into the spotlight.
At a gig the other night a someone wanted to show me a trick and I say “yes”.
They did the trick with the glide where at the end the slap the cards out of your hand and one card is left in your hand and it’s the selected card. When I let her do it, she nailed it! That’s going to be one of the memories from the party for the dozen people that say it, and something they’ll talk about longer than my roving set.
I’m not saying you should 100% always let the person show you the trick. There are times when it’s inappropriate, like in the middle of a ticketed formal show. but if you’re roving or after a show, why not? It’s not going to hurt anything.
